Simmered Kabocha Squash Recipe
Introduction
Simmered Kabocha Squash is a comforting Japanese dish that highlights the natural sweetness and creamy texture of kabocha pumpkin. With a gentle simmer in a flavorful broth, this simple recipe brings out the best in the squash for a warm, inviting side dish.

Ingredients
- 1/2 Kabocha squash pumpkin
- 2/3 cup water
- 1 tablespoon sugar
- 1 tablespoon sake
- 1 1/2 tablespoons soy sauce
- 1/2 tablespoon mirin
Instructions
- Step 1: Peel the kabocha squash and remove the seeds. Cut it into even-sized chunks for even cooking.
- Step 2: Round off each corner of the kabocha pieces to prevent sharp edges and help them cook evenly.
- Step 3: Place the cut kabocha squash in a cooking pot with the skin side down. Arrange the pieces closely without overlapping or leaving gaps.
- Step 4: Add 2/3 cup of water to the pot and bring it to a boil over medium heat. Then reduce the heat and simmer for about 20 minutes, or until the kabocha is tender.
- Step 5: Add the sugar, sake, and mirin to the pot. Bring the mixture back to a boil over medium heat.
- Step 6: Once boiling, reduce the heat to low and stir in the soy sauce.
- Step 7: Place a drop-lid (otoshibuta) directly on top of the kabocha pieces to keep them submerged, then simmer gently for about 10 minutes until fully cooked and flavored.
- Step 8: Optionally, garnish with chopped fresh ginger before serving for a bright, zesty contrast.
Tips & Variations
- For easier handling, use a sharp knife to cut the squash and consider using gloves to avoid the sticky sap.
- If you don’t have sake, dry white wine or a light rice vinegar can be a substitute in a pinch.
- The drop-lid helps the squash cook evenly and absorb flavors; if you don’t have one, you can use a heat-safe plate slightly smaller than the pot opening.
- Add a sprinkle of toasted sesame seeds before serving for extra texture and aroma.
Storage
Store leftover simmered kabocha in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered pan over low heat or microwave until warmed through. The squash may soften further upon reheating, so handle gently.

FAQs
Can I use other types of squash for this recipe?
Yes, but keep in mind that cooking times and texture may vary. Kabocha is preferred for its sweetness and firmness, but buttercup or acorn squash can work as well.
What is a drop-lid (otoshibuta) and can I cook without it?
A drop-lid is a weighted lid that sits directly on the food to ensure even cooking and flavor absorption. If you don’t have one, you can use a small heat-safe plate or foil. Cooking without it may result in uneven flavor distribution.
